Abstract

Briquette is one type of alternative fuel made ​​from various kinds of biomass. Biomass used in this study was the palm kernel shells and palm oil sludge. This research was aimed to make biobriquette charcoal from palm kernel shells and palm oil waste sludge as an alternative fuel and to test the quality of biobriquette charcoal. Testing was performed under non factorial completely randomized design. The parameters observed were calorific value, water content, density and ash content. The results of this study indicated that the composition of biobriquette charcoal affected the calorific value, water content, density and ash content. The average of calorific value was 3714.16 cal/g, the average of water content was 7.95 %, the average of density was 0.79 (g / cm3) the average ash content was 19.84 (%). Keywords : Briquette , palm kernel shells ,sludge, waste

Abstract

Pineapple is a unique tropical fruit. Beside it has sharp scales on its skin, it also has a juicy texture and it has sharp eyes through the outer flesh. This research was held to modify and to expand the pineapple peeler in order to simplified pineapple peeling with ring blade so we could peel a pineapple better and to compare the result to the previous blade. As the name, this blade has shaped like a ring and the cutting side was honed and was sharpened. The capacity of pineapple peeler using ring blade was 39,05 kg/hour. The criteria of peeled pinapple could be seen that there was no pineapple eyes on the outer flesh of the fruit. Losses fruit percentage using ring blade was 33,30%. Keywords : modification, pineapple peeler. : ring blade

Abstract

Capacity constraints of Mechanical cofee skin peeler is one of the obstacles in increasing coffee production. To overcome this, we need a mechanical coffee skin  peeler that has been modified. The study was conducted with the study of literature and make observations about the mechanical coffee skin peeler that has been designed Johanes Mikael Manulang, and then designed the coupling components that would be modified. The effective capacity of the tool was 206.57 kg/h or 1441.44 kg/day. The value of the effective capacity of the equipment was greater than the previous coffee skin peeler i.e 117.39 kg/h or 821.73 kg/day. Basic costs to be incurred was Rp. 73 953 /kg in year 1, Rp. 68.917 / kg in year 2, Rp. 67.241/kg in year 3, Rp. 66.404 /kg in the 4th year, and Rp. 65.903 /kg in the 5th year. This equipment would reach the break even point after peeling coffee at 9124.41 kg/year. Net present value of these equipment with 6% interest rate was Rp. 279,299,067.30 which means that the business is feasible. Internal rate of return was 7.21%.   Keyword: modification, pulper equipment, skin
